The Black and Bloom project examines the role that microbes might have in darkening the Greenland ice sheet – and boosting its melt. UPI talks with Lamont's Marco Tedesco about the forces driving melting in Greenland.

The second large-scale fire in California this week is raging through the southern part of the state, and flooding in Louisiana is worsening. Combined with the fact that this past July was the planet’s single hottest month recorded, are these events indicative of climate change? New Hour talks with Lamont's Adam Sobel.

Over 2 feet of rain in less than 72 hours caused historic flooding in Louisiana this week. Chris Mooney talked with Lamont's Adam Sobel and other scientists about connections between the storm and our warming planet.

Greenland and its ice sheet have warmed briskly in recent years, and this summer has been warmer than normal. But in July’s final moments, at the apex of Greenland’s ice sheet, the mercury plunged to 23 degrees below zero (-30.7 Fahrenheit). Lamont's Marco Tedesco and other scientists explain why a short cold snap doesn't make a trend.

Lamont's Adam Sobel explains that the lack of hurricanes making landfall in the U.S. in recent years is a relatively short-term fluctuation. The projections for increased storm intensity are for long-term global trends.

Lamont's Marco Tedesco views the Arctic as a systems engineer would. He has been trying to “close the loop” and connect the exceedingly complex interactions that drive the northern climate system, which includes its sea ice, atmosphere and ocean circulations, and land ice.

A new analysis of cyclone data and computer climate modeling, led by Lamont's Adam Sobel, Suzana Camargo, Allison Wing and Chia-Ying Lee, indicates that global warming is likely to intensify the destructive power of tropical storms.

A group of scientists studying a broad range of Arctic systems — from sea ice to permafrost to the Greenland ice sheet — gathered in D.C. to lay out just how extreme a year 2016 has been so far for the northern cap of the planet. “I see the situation as a train going downhill,” said Lamont's Marco Tedesco. “And the feedback mechanisms in the Arctic [are] the slope of your hill. And it gets harder and harder to stop it.”

The risk of rapid coastal subsidence to infrastructure and economies is global and is most acute in large river deltas, which are home to about 500 million people. An international community of researchers is calling attention to the need for better measurements and modeling and linking the science with its socioeconomic implications, Lamont's Michael Steckler and colleagues write.

Lamont's Colin Stark visited the Glacier Bay landslide and said closer inspection revealed two big discoveries: the slide was still active days later, and the original landslide was so powerful it pushed rock and dirt up the sides of the valley almost 300 feet.

It's the second summer for the Biking While Breathing project which looks at the impact of air pollution on exercise in New York City. This year, researchers are considering going cheap. Cites Steve Chillrud's work.
